4475,Captured Windows 7 mouse pointer cannot be moved below a certain line,richardcavell,,"Hi, all.
I am running Windows 7 inside a VM. Before I have installed guest additions, I can operate the mouse pointer by clicking on the VM window, and letting it capture my mouse pointer. My mouse pointer cannot be scrolled beyond the edges of the guest OS' root window (which is of course the expected behaviour). However, frequently the mouse pointer finds an invisible lower boundary that is somewhere within the guest display... it's as though the virtual machine thinks that it has found the lower edge of the guest's root window, but it has not. The lower boundary is not at a reproducible location. It can be near the top of the screen or near the bottom. The problem can be solved by just wiggling the mouse pointer until the invisible boundary disappears.
I have confirmed this behaviour on VBox 2.1.4 and 3.0.2 within Ubuntu 9.04 64-bit, and also within VBox 2.20 on Mac OS X. The behaviour is completely fixed by installing guest additions. I have not tested any OS other that Windows 7 (32-bit). I have installed Win7 multiple times and reproduced the problem every time. I never get this problem outside of VBox. I'm running on a MacBook that uses an appletouch touchpad, for the record, but I'm pretty sure that it's not the host OS that's at fault.
